Car insurance groups in the UK are a system used by insurance companies to categorize vehicles based on their risk of being involved in an accident and cost to repair. These groups are assigned letters, starting from A (cheapest) to the highest.
It's possible you've misheard or misunderstood the information. Could you please provide more context? For example:
* Where did you hear about "Group N"? (Website, advertisement, etc.)
* What car were you looking at?
* What was the context of the information?
Knowing more details will help me understand what you're asking and give you a more accurate answer.
